MTA Networking Fundamental

You'll probably be pretty safe memorizing around 15 - 20 ports.
- https://www.microsoft.com/en-us/learning/exam-98-366.aspx which is list exam skills measured only generically calls out:
- Understand the Open Systems Interconnection (OSI) model
OSI model; Transmission Control Protocol (TCP) model; examples of devices, protocols, applications, and which OSI/TCP layer they belong to; TCP and User Datagram Protocol (UDP); well-known ports for most used purposes (not necessarily Internet); packets and frames.
- Understand the Open Systems Interconnection (OSI) model
-
Though none are specifically identified: I would make sure I learn the following in no real particular order. The list though is probably more than enough for the MTA exam...if you can get this list memorized now, you never miss a port number question on CompTIA A+, Network+ and for the most part Security+
